The southern province of Guangdong has long been subject to endemic mosquito-borne diseases. In recent years, this region of China has experienced rapid, extensive economic development involving environmental change, making much of the scant knowledge of its mosquito fauna obsolete. This paper reviews previous mosquito surveys, some of which may be too old to be of relevance to present-day conditions, and presents the results of a recent survey of adult and immature mosquitoes. The main vectors of mosquito-borne diseases endemic to the area, such as dengue and Japanese encephalitis virus, develop in container habitats. A three-year survey was carried out, between 2004 and 2006, of 4131 breeding containers in residential areas and in open, sparsely populated areas, of which approximately 50% were positive for the presence of mosquitoes, and 10 156 larvae and pupae were collected and identified. Twelve species were found in both residential and sparsely populated areas: Aedes albopictus (Skuse) (Diptera: Culicidae), Ae. lineatopennis (Ludlow), Ae. vexans (Meigen), Tanakaius togoi (Theobald), Culex barraudi Edwards, Cx dispectus Bram, Cx malayi (Leicester), Cx pallidothorax Theobald, Cx quinquefasciatus Say, Cx sitiens Wiedemann, Lutzia fuscanus Wiedemann and Tripteroides bambusa (Yamada). Armigeres subalbatus (Coquillett) was found only in containers in villages, whereas Ae. macfarlanei Edwards, Cx mimeticus Noé, Cx sinensis Theobald, Cx vegans Wiedemann, Cx wilfredi Colless and Mansonia uniformis (Theobald) were found only in non- or sparsely populated areas. In residential areas, the rank order of most common species, as measured by the proportion of containers colonized, was Ae. albopictus > Cx quinquefasciatus > Lu. fuscanus, whereas in sparsely populated areas the rank order was Cx quinquefasciatus > Ae. albopictus > Lu. fuscanus. Light traps in non- or sparsely populated areas caught 5995 adult mosquitoes of 25 species, some of which are not container breeders. The most common species were: Anopheles sinensis Wiedemann, An. maculatus Theobald, An. minimus Theobald, Ta. togoi, Cx bitaeniorhynchus Giles, Cx malayi, Cx quinquefasciatus, Cx sinensis Theobald, Cx sitiens, Cx tritaeniorhynchus Giles and Lu. fuscanus. It is noteworthy that nine species caught had not been previously recorded in Guangdong Province, highlighting the deficient knowledge of the current composition and distribution of the mosquito fauna of this part of China.
中国南方省份广东长期以来一直受蚊媒疾病流行的影响。近年来,中国的这一地区经历了快速、广泛的经济发展,其中涉及环境变化,使得对其蚊虫种类的现有稀少认识大多过时。本文回顾了以往的蚊虫调查,其中一些调查可能年代过于久远,与当前情况无关,并展示了近期对成蚊和幼蚊的调查结果。该地区流行的蚊媒疾病(如登革热和日本脑炎病毒)的主要病媒在容器栖息地中生长。在2004年至2006年期间,对居民区和空旷、人口稀少地区的4131个繁殖容器进行了为期三年的调查,其中约50%的容器中有蚊子,共收集并鉴定了10156只幼虫和蛹。在居民区和人口稀少地区均发现了12种蚊子:白纹伊蚊(Skuse)(双翅目:蚊科)、线条伊蚊(Ludlow)、骚扰伊蚊(Meigen)、东乡伊蚊(Theobald)、巴拉迪库蚊(Edwards)、分歧库蚊(Bram)、马来库蚊(Leicester)苍白胸库蚊(Theobald)、致倦库蚊(Say)、海滨库蚊(Wiedemann)、棕头库蚊(Wiedemann)和竹生杵蚊(Yamada)。伪杂鳞库蚊(Coquillett)仅在村庄的容器中发现,而麦克法伦伊蚊(Edwards)、拟态库蚊(Noé)、中华库蚊(Theobald)、素食库蚊(Wiedemann)、威尔弗里德库蚊(Colless)和单色曼蚊(Theobald)仅在非人口密集或人口稀少地区发现。在居民区,按被蚊子占据的容器比例衡量,最常见的蚊种排序为:白纹伊蚊>致倦库蚊>棕头库蚊,而在人口稀少地区,排序为:致倦库蚊>白纹伊蚊>棕头库蚊。在非人口密集或人口稀少地区的诱蚊灯捕获了25种5995只成蚊,其中一些不是在容器中繁殖的。最常见的蚊种有:中华按蚊(Wiedemann)、多斑按蚊(Theobald)、微小按蚊(Theobald)、东乡伊蚊、带喙库蚊(Giles)、马来库蚊、致倦库蚊、中华库蚊、海滨库蚊、三带喙库蚊(Giles)和棕头库蚊。值得注意的是,捕获的9种蚊子此前未在广东省有记录,这凸显了对中国这一地区蚊虫种类当前组成和分布的认识不足。
